CLR is the Common Language Runtime in .NET framework responsible for managing execution of code.

CLR stands for Common Language Runtime and is the virtual machine component of the .NET framework
It provides services such as memory management, exception handling, and security
Managed code is code that is executed by the CLR, while unmanaged code is executed outside of it
Garbage collection is the process of automatically reclaiming memory occupied by objects that are no longer in use
List is a generic collection in C# that stores elements in a specific order
SingleOrDefault returns the only element of a sequence, or a default value if the sequence is empty
FirstOrDefault returns the first element of a sequence, or a default value if the sequence is empty
